I don't think e-hailing would affect the warranty of the car. Warranties are actually covering any defects due to production for a limited period or mileage (whichever comes first for some brand).

Basically, e-hailing increase your mileage and risk of accident dramatically, which will affect your warranty passively. Do note that, if your car involved in an accident & repaired by 3rd parties, the OEM will use this as an excuse to void the warranty for the particular parts.
